Text book/workbook?

Hi all, I am going to re-start my studies after few years. There’s been a lot of changes in almost everything since my last exam. I just need help with BPP books description. It used to be BPP text book before but I can’t seem to find it now. I can see “workbook” everywhere, is it the same as text book with new title or text book still exists and workbook is different? I hope my question makes sense?

Thanks
